QUESTION NO : 11

Which three statements are true about the operation of a full-duplex Ethernet network? (Choose three.)

A. There are no collisions in full-duplex mode.
B. A dedicated switch port is required for each full-duplex node.
C. Ethernet hub ports are preconfigured for full-duplex mode.
D. In a full-duplex environment, the host network card must check for the availability of the
network media before transmitting.
E. The host network card and the switch port must be capable of operating in full-duplex mode.

Answer: A,B,E

Explanation:

Half-duplex Ethernet is defined in the original 802.3 Ethernet and Cisco says you only use
one wire pairwith a digital signal running in both directions on the wire. It also uses the CSMA/CD protocol to help prevent collisions and to permit retransmitting if a collision does occur. If a hub is attached to a switch, it must operate in half-duplex mode because the end stations must be able to detect collisions. Half-duplex Ethernet—typically 10BaseT—is only about 30 to 40 percent efficient as Cisco sees it, because a large10BaseT network will usually only give you 3- to 4Mbps—at most. Full-duplex Ethernet uses two pairs of wires, instead of one wire pair like half duplex. Also,
full duplex uses a point-to-point connection between the transmitter of the transmitting device and the receiver of the receiving device, which means that with full-duplex data transfer, you get a faster data transfer compared to half duplex. And because the transmitted data is sent on a different set of wires than the received data, no collisions occur. The reason you don’t need to worry about collisions is because now Full-duplex Ethernet is like a freeway with multiple lanes instead of the single-lane road provided by half duplex. Full-duplex Ethernet is supposed to offer 100 percent efficiency in both directions; this means you can get 20Mbps with a 10Mbps Ethernet running full duplex, or 200Mbps for FastEthernet.

Cisco’s Networks Will Analyze Us

Cisco Systems announced Thursday that requires Analytics connected a combination of hardware, software and services based on sensor data services. The idea is to provide a quick analysis of the rapid development of information, such as those to be sold by a company, or a beer at a stadium, so that companies react in time.

The strategy can also be a way of Cisco, celebrated his 30th birthday on Thursday more money from the transmission of data is extracted installed for customers. Connected analysis involves a significant amount of computer processing of the data in the vicinity of the action is bound to machinery Cisco network. Cisco argues that this is faster and more efficient than sending everything to a central process computer.

Analytics is still very centralized, but the data locally, Michael Flanagan, general manager of business analysis Cisco. There will be more and more applications where the edge analytics are important. He cites a great merchant, the movement of people through their shops pursued. When many people bought in the frozen food department, said that you can check on what they were.

(You have things that melt in your shopping cart, while the cookies are not.) That was a signal to increase the number of ATMs. In the case of a football stadium, information could Wi-Fi handsets to say about movements and personal consumption. Are the fans in the pilot's seat behave like a nosebleed? Flanagan said. You have information on the application data, often people watching Facebook. While it is the responsibility of the customer how to use these data, he said, you can Gran Hermano go very fast.

Cisco's goal almost certainly cash, not coercion. The company also sells analyzing how is running your own data network, enabling customers to their systems to work more efficiently. In cases of primary, it is likely that the attached analysis not even a new hardware in some Cisco networks, but makes the most valuable gear for a customer.

The Cisco announcement is part of a broader trend by mature tech companies to make new businesses by looking at the behaviour of machines and people. Mr.Flannagan’s group, created as a part of Cisco’s services division just six months ago, already has 450 people.

Earlier Thursday, General Electric announced a deal with SoftBank of Japan to resell G.E.’s analytics product, called Predix. SoftBank was a particularly attractive partner to G.E. because it is a telecommunications service provider. If you are already shipping the bits, perhaps looking at them is a natural fit.

The G.E. business is primarily built around insights from industrial machinery, like power generation equipment. While Cisco’s examples deal primarily with human behaviour, the company has also sold analytics for things like oil rigs.
